actionchain: ingest failure: trufflehog (upstream broken) #4786
Description
All 6 CI check failures are caused by a transient GitHub infrastructure error (HTTP 500 Internal Server Error) during the git fetch step of the actions/checkout action. The error message is: "fatal: unable to access 'https://github.com/dlorenc/actionchain/': The requested URL returned error: 500". The tests never executed - they all failed before even checking out the repository code. This is a GitHub server-side issue that would resolve on retry, not a problem with the action or test code.
